如何在我的大聯接Mysql查詢中使用where子句限制結果？

Question

我已經在下面成功編寫了此聯接查詢，以在一個查詢中從數據庫的每個單獨表中獲取所需的所有數據。 不幸的是，它給了我來自這些單獨表的所有數據。 如果e.Design_ID = 1，我僅需要與e.Design_ID對應的數據，但是我在此代碼塊中嘗試了一些“ where e.Design_ID = 1”，但未成功限制查詢。 我被卡住了。 我在想可能需要重組整個查詢。 我的邏輯可能不對...

任何幫助深表感謝。

SELECT 
a.SKU,
a.Apparel_ID,
a.Apparel_Color_Abbr,
a.Design_ID,
a.City_ID,
a.Category_ID,
a.SEO_Keyword,
a.OC_Product_ID,
b.Apparel_Color_Palette,
b.Apparel_Name,
b.Apparel_Name_Abbr,
b.Apparel_Type,
b.Google_Feed_Cat,
b.Gender,
b.Age_Group,
b.Retail_Price,

FROM Complete_City_Products AS a
INNER JOIN Apparel AS b ON a.Apparel_ID = b.Apparel_ID
INNER JOIN Apparel_Colors AS c ON b.Apparel_Color_Palette = c.Apparel_Color_Palette AND a.Apparel_Color_Abbr = c.Apparel_Color_Abbr
INNER JOIN Cities AS d ON a.City_ID = d.City_ID
INNER JOIN Designs AS e ON a.Design_ID = e.Design_ID
";

INNER JOIN Cities AS d ON a.City_ID = d.City_ID
INNER JOIN Designs AS e ON a.Design_ID = e.Design_ID

WHERE e.Design_ID = 1
";

如果放在最后，它應該可以工作。 還要檢查正確的拼寫。
